[ About Us ]

Welcome to ZOK

Our mission is to provide high-quality welding, metalworks, and corrosion protection with reliability and expertise.

Company Z.O.K. d.o.o. has been founded in 1999., as the answer to growing demand for high end quality suppliers in corrosion protection field. This trend has first been noticed in shipbuilding industry segment, where we’ve been engaged continuously from the company startup.

With development, our expertise has spread to other fields, mainly steel and aluminium production segment. New developments have also raised request for new skills and standards implementation from our employees. This fact has added greater value to company and, consequently, opened new niches in market.

Z.O.K. d.o.o. currently employs around 90 professional painters, sprayers, locksmiths, shipbuilders, pipe fitters and welders. The company workers are trained to deliver requested quality, firm reliability and professional responsibility, for mainly dealing with demanding tasks and top-end business partners.

Welding

Welding

Arc welding is most widely used fusion process for joining metals. In arc welding, the intense heat needed to melt metal is produced by an electric arc. The arc is formed between the actual work and an electrode (stick or wire) that is manually or mechanically guided along the joint.

However, joining metals requires more than moving an electrode along a joint. Besides some form of arc shielding, welder ‘s knowledge and experience play the crucial role. Therefore, our welders are strictly kept in groups concerning materials and processes. As for the materials we have specialist for mild, stainless and galvanised steel, as well as aluminium. Each of these materials our welders join or repair by shielded metal arc (SMA), metal inert gas (MIG), metal active gas (MAG) and tungsten inert gas (TIG) processes. Needless to emphasise, that each and every single welder is certified by some IACS member class society, while all the procedures are determined and controlled by international welding engineer (IWE).

Metal construction

Metal construction

Our services include production of ship hull, superstructure, equipment and foundations in addition to piping production, welding and assembling.Besides marine constructions we have gathered expertise in welding and assembling of various metal erections, bridges and structures for the list of long-term partners. In ever changing business, diversification calls for flexibility, mobility, continuous quality and at work safety. We may only rely on expertise and responsibility in carrying out these new challenges. Let us also mention what has gained us the trust with the clients: swift response to urgent requests for welders, fitters or any other metal professional in our team. Big Croatian shipyards are our long-term partners in the field.

Over the years we have gained the experience in ship sections, piping and equipment production and our partners entrust as the most complicated parts throughout. Armed with the experience, know-how, recommendations and some confidence we have lately entered demanding EU market and are still firmly holding our place in several north European shipyards.

Corrosion protection

Corrosion protection

An understanding of corrosion and development of a corrosion engineering science has come about due to the need to protect materials from disintegration by normal breakdown processes. Atmospheric rusting, chemical solution, oxidation, and galvanic coupling reactions, are the means by which materials return to their original state.

Tremendous amount of energy used to convert them from their original form to one usable by humans remains latent in the material and is released at every opportunity as the material reverts to a state of equilibrium with nature. Everyone in modern society is affected, in some way, by this energy release phenomenon, or corrosion. Control of this reversion process is the goal of corrosion engineering.

Quality standard

Quality standard

In order to fulfil and upkeep ever increasing industry standards we have adopted and implemented integrated quality management, environmental protection systems and occupational health and safety according to international norms ISO 9001, ISO 14001 and ISO 18001. Project Managers are all certified FROSIO corrosion protection inspectors, while Class societies inspects and test our welders. Oil and gas industry recognises Achilles as a name trusted by procurement communities the world over, and we have been for years now, awarded reliable supplier status in their listings.

Nevertheless, we’re well aware that the greatest value within our firm are our professional, educated and motivated 80 long-term employed workers. All of them are well trained to work under legal safety standards and fire protection hazards.
